I just played this one recently, it is an arcade flash game created by Snubby Land, consisting of around 30 levels and players can only submit their scores after completing all the 30 levels. The game is very tough indeed though the first few levels can be passed without breaking a sweat.
GAMEPLAY
The gameplay is pretty simple, you just have to move a red square with the help of arrow keys, avoiding the blue circles which are not stationary and collecting the yellow circles which are stationary, after that you need to reach the green beacon(intermediate ones can act as checkpoints) for completing the level. You get one death if your square hits the blue circle and you will be transferred to the last checkpoint you were in, if you have less deaths after 30 levels, the better your score will be.
So give it try if your looking for a real challenge.8D
